CVE-2025-48038: CWE-770 Allocation of Resources Without Limits or Throttling in Erlang OTP
Allocation of Resources Without Limits or Throttling vulnerability in Erlang OTP ssh (ssh_sftp modules) allows Excessive Allocation, Resource Leak Exposure. This vulnerability is associated with program files lib/ssh/src/ssh_sftpd.erl. This issue affects OTP from OTP 17.0 before OTP 28.0.3, OTP 27.3.4.3 and OTP 26.2.5.15, corresponding to ssh from 3.0.1 before 5.3.3, 5.2.11.3 and 5.1.4.12.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-48038) in Erlang OTP concerns the ssh subsystem, specifically the ssh_sftp modules, where resource allocation occurs without proper limits or throttling controls. This flaw can cause excessive allocation of system resources or resource leaks, potentially degrading system performance or availability. The affected code is located in lib/ssh/src/ssh_sftpd.erl. The vulnerability affects OTP versions starting from 17.0 up to but excluding 28.0.3, including patch versions 27.3.4.3 and 26.2.5.15, and corresponding ssh versions 3.0.1 before 5.3.3, 5.2.11.3, and 5.1.4.12. The CVSS 4.0 base score is 5.3, indicating medium severity. There is no vendor advisory or patch information available at this time.
Potential Impact
The vulnerability allows an attacker to cause excessive resource allocation or resource leaks in the Erlang OTP ssh subsystem, which may lead to degraded system performance or denial of service conditions due to resource exhaustion. There are no reports of known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider monitoring resource usage related to ssh_sftp services and applying any recommended configuration limits if possible. Avoid exposing vulnerable versions to untrusted networks.
